Abstract: The present invention relates to a kit useful for separating and/or characterizing at least one molecule A of interest, said kit comprising at least: (i) a compound of the following general formula (I): B-(R)n-Z (I) in which: B represents a hydrogen atom or a detectable labelling entity; R represents a C1-C10000 hydrocarbon unit which may be alternatively polymeric or non-polymeric and optionally incorporate one or more heteroatoms, chosen from N, O, S, Br, Cl, F, P, B, Si and/or one or more metals; n represents 0 or 1, with n being equal to 1, when B represents a hydrogen atom; and Z represents a functional group capable of reacting in a click chemistry reaction in order to form a linking function Lclick; and (ii) a molecularly imprinted polymer dedicated to the molecular recognition of at least said linking function Lclick.URL: http://v3.espacenet.com/publicationDetails/biblio?DB=EPODOC&adjacent=true&locale=en_gb&FT=D&date=20100318&CC=WO&NR=2010029504A1&KC=A1
